Brain Structures
BIO 208: A&P - Lab: Chap 7, Brain Structures and Functions
| Brain Structure | Function |
|---|---|
| Cerebrum | Controls thought, memory, and senses |
| Cerebellum | Maintains muscle tone, balance, and coordination of movement |
| Brain Stem | Medulla Oblongata, Pons, and Midbrain |
| Medulla Oblongata | Contains autonomic centers that control heart rate, respiration, and swallowing |
| Pons | Links Medulla Oblongata and Thalamus. Sleep, respiration, bladder control, equilibrium, posture. |
| Midbrain | Relays information for vision and hearing |
| Diencephalon | Hypothalamus and Thalamus |
| Anterior Pituitary | Secretes growth hormone |
| Posterior Pituitary | Secretes anti-diuretic hormone and oxytocin |
| Hypothalamus | Important autonomic and neuroendocrine control center |
| Thalamus | Gray matter. Recieves auditory, somatosensory, and visual sensory signals. Sleep/wake states. |
| Optic Chiasma | Where optic nerves meet |
| Optic Nerve | Relays visual information to the brain |
| Olfactory Bulb | Relays smell information to the brain from the nose |
| Ventricles | Holds spinal fluid |
| Spinal Cord | Relays information between brain and body |
| Corpus Callosum | Band of tissue that connects the 2 hemispheres of the brain |
| Gyri | Ridges of the cerebrum, increase surface area |
| Sulci | Depressions of the cerebrum, increase surface area |
